Can't afford to burst pipe
The tubing of the high reach demolition boom excavator is equivalent to the blood vessels of the human body. Whether the tubing is burst, damaged or aging, it will have a huge impact on the operation and construction of the machine. It can also be said that 100 of 100 pilots are unwilling to deal with sudden tubing burst failure.
The reason is also very simple. If the construction site is very remote, the job is to stop and wait after the tubing burst, so the loss is very huge. Therefore, the careful owner will check regularly and prepare spare parts at any time, but these are not coups once and for all. Today we will carefully talk about why the tubing always bursts! What methods can be easily prevented.
Poor quality of hydraulic pipe
Let's first understand the causes of tubing bursts, and we must start with the root causes to deal with tubing bursts.
The first reason is that the quality of the tubing is not up to standard. Of course, this reason has zero chance of appearing on the new machine, but it happens very often on the old machine and the second mobile phone. Quite a few owners feel that the machine is older and the replacement cost is The lower the better, so when the original high-quality tubing is damaged, it is most likely to buy low-priced tubing.
It is conceivable that the quality of the processing technology and metal joints of this part of the tubing is not up to expectations, let alone the airtightness, so the service life and effect are very worrying! So don't spend more money to remedy it just to save a small amount of money.
High hydraulic system pressure
There are also a considerable number of friends who manually adjust the pressure value in order to make the machine construction work more powerful and efficient, but there is one thing you must not ignore. The pressure value at the factory is set based on the limits of the operation of each component. Yes, if you increase the pressure of the hydraulic system alone, once the load-bearing limit of the hydraulic pipe is exceeded, it is only a matter of time before the pipe bursts.
Therefore, do not adjust the pressure value of the hydraulic system set by the factory at will. If you need to adjust due to a failure, you must also do it under the guidance of a professional master to avoid unnecessary failures.
The hydraulic oil temperature is too high
Excessive hydraulic oil temperature is also a major cause of pipe bursts, and there are many reasons for high oil temperature. We will not repeat them here, but there is a special reason that I hope everyone will pay attention to-mixing hydraulic oils of different labels.
For example, if the new machine is filled with No. 46 hydraulic oil when it leaves the factory, do not add No. 68 oil frequently during the daily construction process, because the viscosity and oil quality of the hydraulic oil will be affected over time. Excessive temperature can also cause the tubing to burst! Even hydraulic components can have an impact.
Bad operating habits
I believe that every construction site will have an old driver with too much hands and too much operation. It seems that the operation is fierce. In fact, this wrong operation habit will also contribute to the explosion of the oil pipe, because the instant increase in force will It produces a huge impact. If the tubing has problems such as aging and cracks, the probability of tubing burst will be greatly increased.
Of course, the bursting of the tubing is just an intuitive negative effect caused by violent operation. In the long run, hydraulic components will be more or less affected, and the service life will be greatly reduced.
Abnormal vibration of pipeline
Pipeline vibration is inevitable during construction. After all, high reach demolition boom excavator have been engaged in difficult and dangerous working conditions for a long time. Moreover, both gear pumps and plunger pumps have oil pulsation. This pulsation will cause high-frequency vibration of the hydraulic pipes, which will cause fatigue and wear of the hydraulic pipes for a long time.
Of course, although this unavoidable vibration cannot be avoided, there are also remedial measures. Usually, the operator of the construction gap should always check the pipe clamps and protective sleeves of the hydraulic pipeline to prevent the hydraulic pipeline from wearing.
Hydraulic pipe burst remedy
If a pipe burst occurs, how can we quickly solve it with the least cost! First of all, as soon as the pipe burst occurs, we must ensure that there is not too much oil loss, and the operator must calmly deal with it! Put the bucket on the ground first, then stop the engine and turn off the flame to reduce the pressure in the system and slow down the loss of hydraulic oil.
If you do not have good conditions on the construction site to replace the tubing immediately, you must quickly take a temporary remedy. If the pressure of the hydraulic system is between 25-8.0MPa, you can use the method of sticking.
Generally, everyone uses first to wipe clean the broken part of the hose to ensure that there is no oil and other infestation, and then apply "anaerobic" glue, "epoxy resin" glue, "801" glue or "502" glue. In one of them, find the tape strips and wrap them firmly. It is best to apply a layer of glue to each layer of tape strips for reinforcement, but this method can only be used as a temporary remedy.
